The wooden surface must be dry, carefully sanded and cleaned from dust and other impurities.
Stir thoroughly both before use and between the applications, but be careful not to let air into the product. Brush application is recommended. Prime with diluted HELO AQUA 80, if needed. Apply first a thin coat of HELO AQUA 20 varnish and let it dry for at least one hour. Sand the surface and remove all sanding dust carefully. Apply a second coat of varnish and let dry for about 3 hours before applying the third coat. Untreated wooden plank floors: Prime with 15 % diluted HELO AQUA 80 using brush or trowel. Finish with 2 - 3 coats of 10 % diluted HELO AQUA 20 using brush or trowel. Spread out the varnish in the direction of the pattern and the grain of the wood. Previously varnished floors: It is recommended that the surfaces are sanded to bare wood and that the instructions above for untreated wooden plank floors are followed. If the old varnished coat is in good condition HELO AQUA 20 varnish can be applied according to the instructions for finishing to a surface that has been carefully sanded (sanding paper no. 150 or finer). In this case, however, the varnish is first to be tested on a small area to ensure proper adhesion.
During the application and drying period the temperature of the ambient air, the surface and the product shall be above +10°C and the relative air humidity below 80%.
Must not freeze.
